NETWORK BASED REAL-TIME FLY-THROUGH ON MASSIVE TERRAIN DATASET

摘要

A solution was presented in this paper to realize fly-through on massive terrain dataset under the circumstance of computer network. The multi-resolution vision field template, based on localized feature of vision field and characteristics of human vision, could decrease the requirements significantly of real-time fly-through to bandwidth and graphic capability of terminal, if slight loss can be tolerated. Several technologies was introduced including network oriented massive terrain dataset organization, view dependent multi-resolution vision field template, terrain data transfer protocol and quality of service control. Finally, an instance system is implemented.
